Power, blinking green light, motherboard plug in

My comjputer has failed to start when the green light on the back of the computer flashes. i tried the suggested hair dryer trick and it didn't work. I did find that if i disconnected the power cord and disconnected the large connection to the mother board then plugged the power cord in followed by plugging the connection to the motherboard in I was able to restore a solid green light and start the computer. I have not tried flipping the red switch on the back, i'll try that next time.
My question is: Has anyone tracked this problem down to its source yet? Is it a power unit issue? Or is it a motherboard issue? Does replacing the power unit solve the problem?
Also, do I need to replace this unit or the motherboard soon?
Most of the posts about this are older. Is this no longer a problem for most folks?
any and all help will be appreciated, thank you.

While the Insignia PSU should work (I looked at the specs), I did not find any efficency rating. It's also a 1 year warranty. Trying to find the real manufacturer is a puzzle, as it's an in-house Best Buy exclusive. The Corsair is energy efficient >80%, and has a 3 year warranty. Here's a vendor list, and who really makes what PSU.

Desktop won't start; blinking green light

I have a Compaq Presario SR 1318NX which will not start!? There is a blinking green light on the back of the power supply; which is normally solid green when 110V AC is plugged into it. I have tried the trick of holding the start button while plugging in the power cord ..... no help. I have also opened the case and carefully removed every power cord to all the internal devices ................ the light turns solid green only when I pull the main power from the motherboard!
Do I need to replace the motherboard? The troubleshooting site on hp.com would indicate the power supply is OK if the light is solid green.
Thanks for any suggestions,
Lou

My wife's computer has been having the same problem several times. One solution I found that worked before was to unplug the motherboard power cable and the PSU power cable from the back of the PC and then connect the power cable and connect the motherboard power cable while holding down the power button. Scary, to say the least, but it worked, until one day I accidentally flipped the wrong breaker and then spend two hours trying the same solution with no luck and Googling again. And here is what I found. This is the simplest yet crudest solution. It’s easy and non invasive and it doesn’t matter how tech savvy you are. Take a blow dryer and turn it on to blow air at the back of the power supply for a couple minutes. When you see the light turn green you’re all set. It's worked for me after it worked for a hundred others, maybe more. See the testimonials on this site: http://talk19.wordpress.com/2008/01/13/hp-m7088d-power-supply-led-blinks-green/. It’s a shame that nothing like this appears on any HP site. So don’t waste your money on a new MoBo or PSU. All you need is your wife’s hair drier.

Background contrast on Apps screen & blinking green light

Newbie here. The Apps screen had a blue background but is now white and I am unable to read the titles of the icons at the bottom of the screen. How can I get rid of the white background and return to the blue contrast?
Additionally the green indicator light is blinking non-stop. Why is it doing that now when it never did before?
Thanks!

Greetings, and welcome to the forums!
Not sure about an answer to your 1st question, but the blinking green light simply means that your phone is connected to your carrier. I use it just so I know at a glance whether my phone's actually on or not. To disable that blinker, go to Options > Screen/Keyboard > LED Coverage Indicator and change the setting to "off".

Blinking LED on AC Power Adapter: green light/ red light, slow recharge?

Once recharge reaches about 90% the LED on the AC Power Adapter starts to blink green and red. The battery icon also flashes between "Charged" and time of remaining charge. Flashing cycle dramatically increases time to fully charge the battery, as if it gets stuck in an infinite loop and can't reach a full charge. A few days ago problem started after the most recent software update. Battery has a mark of corrosion, one small rust looking mark. Power Cycle Count is 329. Unexpected shut down (not sleep) did occur one time when battery was at low charge. BatteryUpdater.bundle is Version 1.3. Battery was calibrated also a few days ago. MacBook is not under the extended warranty. Any idea if this is the battery problem or AC power adapter, or even a glitch in the recent software update?

Hi,
I've the same problem. Once recharge reaches about 95% the led on the Power Adapter keeps blinking.
The battery icon does the same. I also had a sudden shutdown. Battery is not damaged and cycle number is 147. I've tried downgrading BatteryUpdater.bundle from version 1.3 to 1.2, but nothing changed. Any idea about a possible cause/solution?
Thanks,
tom

Device not recognized by Windows or iTunes - Blinking green light

When I try to connect my iPod shuffle to my computer (Windows XP), it's not recognized by Windows or iTunes. (i.e. device does not appear in Windows explorer or iTunes) While in the USB port, the Shuffle's green light blinks incessantly. My wife uses an iPod on this machine (under separate user name) and has no problems.
I've tried updating software (iTunes, iPod), restarting my computer and resetting the iPod to no avail. My machine is not on a network. The USB port(s) work fine as I can use my memory stick (no USB cable) with no problems. I've tried connecting my Shuffle under my user name as well as my wife's. Same problem.
Also, I had my Shuffle setup on an old computer (PC, Windows 2000) and it still works fine plugging into that. (I'm getting rid of it soon, hence why I'm discovering these new problems).
Please advise. Since my Shuffle is over a year old, I am not eligible for online chat or phone support without paying for an Apple Support agreement.
I know there's another thread with the same issue that was not resolved on the discussion board.
Thanks to anyone who can help.

Recently I used my ipod at work all night, just like normal. After work on the way home, like normal, I plugged it into my aux port on my car's head unit, and plugged it into power. 10 minutes later, in the middle of going over Ortgea Highway(hiway 74 between Orange and Riverside Counties), it just suddenly stopped working. When I plug it into any of my computers at home, nothing happens, it is not recognized or seen. When I plug it into power, it displays either a "sad ipod icon" or a battery with exclamation mark(!) icon. I have brand new power adapters both for the car and home, plus brand new usb cables, thinking that would help. It hasn't and now, since I opened those packages, I am out that $$ and ******. Since I received this unit as payment for electrical services rendered, I have no idea how old it is. Does anyone have any ideas? ([email protected])

Why do i get a blinking green light on my airport?

My airport keeps blinking a green light, and my airport utility does not detect a configured airport even though it is plugged in. what should I do?

Please try a factory default reset on the AirPort Extreme as follows:
Pull the power cord from the AirPort
Wait a minute
Hold in the reset button on the AirPort first, and keep holding it in for an additional 8-10 seconds while you simultaneously plug the power back into the AirPort
Release the reset button after the hold period and allow a full minute for the AirPort to restart.
If the AirPort is operational, it will display a solid amber light for about 30 seconds, then the light will turn to blinking amber.
If you still have no power light after you try the reset a few times, the AirPort has unfortunately very likely failed and will need to be replaced.
If you do have an Apple Store near you, take the AirPort to them to let them have a look. If the AirPort has an external power supply "brick", sometimes that is the culprit and new power supply will get things going again.

No power and green light on my hp pavilion is flashing

Hello,
I'm trying to figure out if the power supply on my hp is bad or not. The green light on back of the tower is flashing and the computer won't turn on. I've tried all of the preliminary things and nothing works -- the green light keeps blinking until I disconnect the large plug to the motherboard, then the light stays on and doesn't blink. Once I have the power cord disconnected and the main plug to the motherboard disconnected as well, I then have tried replugging the power cord and then replugging the main plug to the motherboard (kind of trying to jump start it), the fan tries to come one (but only for a second, then goes back off, so it won't boot).
Does anyone know if this means that the power supply is bad or if something else might be wrong? I'm wondering if the power supply would be bad when the computer is clearly trying to start, but not quite making it.
This question was solved.

Blinking Green Light! Mount & Unmount on Intel Mac mini

Hi all.
This is my sister's iPod shuffle, lat night she plugged into her new Intel Mac mini Core Duo, and the shuffle mounts, everything appears to be in working order, she said today she still listened to it.
Just now she accidently plugged the shuffle while in our Dad's account (on the Mac mini as well), then seemed like "all well broke loose", this is what she told me, first iTunes was not responsive, colour wheel, so she restarted but only arrived at the blank desktop and only the shadow of the Top Menu Bar
I reset the iPod shuffle, was successful in plugging it in, quit iTunes (all in her own account now) and update the shuffle software.
When inside iTunes, once I started Autofill, it suddenly unmounted by itself, followed by the red exclamation error message when you accidently remove an external device unproperly.
When I tried plugging in again, it refuses to mount. Just blinking Green, or pull out again, blinking Yellow.
Now I plug it into my own iMac G5, and it mounts and is blinking slowly with yellow light, what seems to be normal charging.
Has this something got to do with the Intel Mac??
Thanks and cheers

This probably has nothing to do with the Mini, but everything to do with the Shuffle. Like all flash memory, it is susceptible to damage if unplugged at the wrong time.
For the shuffle, you cannot remove it while it is updating or in Disk Mode. This warning is presented in the User's Guide and is repeated in several other places throughout the Support pages as well.
The general rule is: If it's blinking amber, don't unplug it before you unmount it. Unmounting can be done either in iTunes or in the Finder.
About all you can do, given the symptoms you're seeing, is try to Restore it. See the instructions in the User's Guide and/or on the iPod Shuffle Support Page.

Apple Wireless Keyboard Blinking Green Light & Not Found

Hi all
I've had a wireless keyboard and mouse for the past 2 years which have given me no problems at all. Suddenly the keyboard has stopped working and when I looked for it on the bluetooth menu it said it wasn't connected. I tried to set it up with Bluetooth again but it can't be found. I replaced all the batteries and when I switch it on the green light blinks on and off for a while (which is when I tried to re-pair it with bluetooth) but then it stops blinking and stays off. Has anyone any ideas? Is the keyboard itself for the trash? The mouse continues to work fine.
thanks
WG

This morning, my Keyboard went into the fast blinking light state when I inadvertently pressed the power button when it was in the middle of pairing.
Here's what worked this time:
• Took out the batteries and left them out for > half an hour.
• Deleted the pairing in the bluetooth preferences.
• Made the MacBook Pro 'invisible' -> turn 'Discoverable' off.
(Because the keyboard tried to pair with the MBP again, which I denied)
• Put the batteries back.
• 'Set up new bluetooth device -> keyboard'
• Turned on the keyboard
• Paired again.

Blinking Green Light

Occasionally after an update, when I turn my iPod on, the power light on the front will display the usual green. However, there will be a pop in the headphones, and the green light will just blink as if it keeps turning on and off. This prevents me from listening to music. Does anyone know what might be causing this?

Hello Everyone.
Thank you for your posts.
While your tablet is asleep, a notification LED light ( the Green Light) will blink when certain things happen that you may want to know about immediately when they occur.
Any of the following events can cause the LED light to blink:
• Calendar: A scheduled time or date has been reached.
• Desk Clock: A scheduled alarm time has been reached.
(This will be accompanied by an alarm sound)
• Email: A new email is received.
• Social Feed Reader: A new post has been made.
• Gmail: A new email is received.
• Talk (Google Talk): A new message is received.
Most of these events can be changed by accessing the settings
Others such as the social feed reader would require you to remove that app from being monitored to prevent notification as that is one of its key functions.
This will not affect the facebook or twitter app, just the social feed app for notification from both services.

Blinking Green lights

I have an Ipod Shuffle 4th Gen and it's only displaying a green light that blinks around every two seconds and won't play any music. I restored the Ipod multiple times and enabled/disabled disk use multiple times, and it still won't play. Is there any way to fix this?
Thank you
Ipod Shuffle 4th gen, Windows 8, latest version of iTunes.

If a factory default reset fails to correct this problem then your diagnosis is right - your Airport Express has failed.

Desktop won't power on/Green light will light up a little/fan spins a little?

Trying to help a friend, with an HP computer. Forgot to get the model number. It won't start up, I can momentarily get the green light on the power supply to go on, and the fan runs momentarily. It won't start up.
Would you think it was the power supply or the motherboard? Any Suggestions.
Thanks Bruce

Hello brucefl,
I have read your post on how your friend's computer will not power on, and I would be happy to assist you in this matter!
Since the fan spins a little bit with the green light, I recommend following this document on Computer Does Not Start (Windows 7) or for (Windows 8). This resource should help power on your desktop, or specify if there is a hardware defect attributing to the issue.
For further assistance, I will need to know:
The Product and Model Number of your desktop computer.
The version of Windows you have installed on your computer.
If this is an on-going, or recent issue.
If you have added any new hardware or software recently to your computer.
Please re-post with the results of your troubleshooting, as well as the requested information above. I look forward to your reply!

Blinking green light and then orange and green at the same time...

I have an Ipod shuffle that was working good before and I don't know why I let it one month and after when I connected it to the computer Windows and Itunes didn't recognized it. It seems to function good because I can listen the songs that were before in the Ipod, and when I don't have battery I connect it to the computer and it seems to charge because after I have battery. The only thing is that when I connect it I don't listen that windows recognize it (like when I connect my USB key) and Itunes neither. Moreover there is a green light blinking two seconds and after green and orange at the same time (little lights) during one second. I can't restore it because it doesn't appear in Itunes.
Do you know what can do that???
Thx

Faites ceci:
- Retirez le Shuffle du socle
- Cliquez sur Démarrer, puis Bouton droit sur "Poste de Travail" et prenez "Gérer" puis double-cliquez sur "Services et applications", puis double-cliquez sur "Services"
-Localisez "Ipod Service", double-cliquez dessus, et cliquez sur le gros bouton "Arrêter" (Statut de Service Smile
-Rebranchez votre ipod, sur le socle.
-Sous Windows, effacez l'intégralité de son contenu. Ou alors faites un bouton droit sur l'icone du "disque" puis formattez.
-Lancez iTunes
-Ce dernier va détecter l'ipod et va vous demander son nom, avec une case en dessous "Remplir automatiquement"
-Laissez cette case validée !
-Pendant que l'ipod se remplit (il convient d'avoir des morceaux dans la bibliothèque iTunes) allez dans longlet "Réglages" de l'ipod, sous iTunes
-Cochez la case "activez l'utilisation comme disque dur"
-Cliquez sur appliquer pour valider cette option !
Vous pouvez maintenant éjecter votre ipod (ne le retirez pas du socle, cliquez sur le bouton approprié sous itunes !) et voilà, tout fonctionnera à merveille !

Power adapter green light no power no charge

Thanks in advance for any help with this; I'm a Peace Corps Volunteer currently serving in rural Cambodia, so it's a little tougher to deal with this problem and/or get an alternative computer.
I had been using my MacBook when I realized that although it was plugged in and the LED was green, the battery was losing charge. I tried cleaning out the connector and magsafe port and doing some other trouleshooting including trying to reset the PRAM and SMC. Eventually I was able to borrow a different adapter from a friend, and that didn't work either, so I know it is not an issue there. At this point, the battery is completely drained, and although the LED still lights green (and sometimes orange for a few seconds after being plugged in), the computer will not turn on at all even when plugged in, so it is not just a battery issue. I've been fiddling with it for about a week and no luck on anything. Other than this problem, everything seemed to be working completely fine until the battery died. From some reading, I'm wondering if the problem may the logic board. If so, does anyone know how much it would cost and how long would it take to fix that problem? Are there any other possible things it could be? I'm in a situation where, luckily, there is an Apple repair place in the capital city, but I can only be there for short periods of time once in a great while. I also don't have access to a whole lot of cash and would need to plan in advance if it will be pricey. My Mac has been great until now and is the way I Skype with family and friends, save photos, watch movies, etc from my Peace Corps village, so it would be really great if I could get it fixed. Thanks for any help!

The "power cord" is just an extension cord to give you more length then plugging in the MagSafe adapter. Leave it plugged in if you don't want to drain the battery, otherwise run on battery.
The "duckhead" slides off of the magsafe so the extension cord can plug into it.
Here's an illustration.

Regza 26LV47 ------- STEADY Blinking green light?

No power-up, no sequence of three blinks like most others.
Any suggestions?

I'm sorry; I must have made a typo when I went to look it up yesterday. I do see it now, but unfortunately, I don't see any information regarding that issue. It does sound like it would require servicing, but specific parts are beyond my knowledge. Sorry!
